Prophet Noah

I have heard that the flood of Hazrat Nuh (as) matches with flood incidents mentioned in history of the Sumerian civilization and in Hindu scripture. And they also talk about a creation story akin to Adam (as). How should we understand such similarities? Amina Inloes	Does the Quran state that the Bani Israel were favoured due to being the progeny of those with Noah (as)? If so, are we not all progeny of those with Noah as everyone else in the world had drowned? Sayyed Mohammad Al-Musawi
Besides the ark of Prophet Nooh (as), what are the other Prophetic things to which the Ahlulbayt (as) have been compared? Sayyed Mohammad Al-Musawi	Is it true that Prophet Nuh (AS) prepared a grave for Imam Ali (AS) 700 years before his martyrdom? Amina Inloes
